The CSF 8154 is a premium aluminium intercooler water radiator that replaces the small factory auxiliary cooler with a high efficiency unit engineered for hard road use and circuit abuse. Ideal for remapped and hardware-upgraded B48 and B58 builds, it delivers colder, more stable intake temperatures for repeatable performance on back roads, track days and the drag strip.\u003c\/p\u003e\n\n  \u003cp\u003eWhether you are on Stage 1, Stage 2 or a big turbo Stage 3 setup, raising boost creates heat that can overwhelm the stock chargecooler loop. CSF’s larger core increases cooling capacity and sheds heat faster, so the ECU does not pull timing and power stays consistent run after run. Expect a typical 5 to 15°C drop in charge temps depending on tune and conditions, plus quicker recovery between pulls and improved airflow through the cooling stack.\u003c\/p\u003e\n\n  \u003cp\u003eWe have installed this heat exchanger on customer cars at MJ Modifications and on our own development vehicles.
